Background:
The intron 5 insertion/deletion polymorphism of Alpha-2-macroglobulin receptor-associated protein gene (Alpha-2-MRAP) has been implicated in numerous diseases. The current study was designed to analyze the association of intron 5 insertion/deletion polymorphism of Alpha-2-MRAP with nephrolithiasis patients.
Methods:
PCR was conducted on genomic DNA of patients and control to look for Alpha-2-MRAP insertion/deletion polymorphism. Besides that, serum level of Alpha-2-MRAP, oxidative stress marker myeloperoxidase, Malondialdehyde (MDA), Advanced oxidation protein products (AOPP), and uric acid were determined.
Results:
The D and I allele frequencies were 57.50% and 42.50% in patients, 77.50% and 22.50% in control, individually. The result showed that II genotype was associated with nephrolithiasis patients group. A significant decrease was observed in serum Alpha-2-MRAP,myeloperoxidase and TAS,while TOS,OSI,MDA,AOPP and uric acid were substantially increased in II and ID when compared to DD genotype in patients with nephrolithiasis.
Conclusion:
Our results demonstrate for the first time that patients with II genotype had an increased risk of stones. Also, the results demonstrate that I allele of the 5 insertion/deletion polymorphism in the Alpha-2-MRAP gene is related with an increase of oxidative stress in nephrolithiasis patients and may possibly impose a risk for cardiovascular diseases in patients with II genotype of Alpha-2-MRAP.
